Hi all. Hardware question:
I opened up the bottom end of my '28 engine. It mostly looks pretty good in there, but some previous owner had the bottom end apart, and used 6-penny nails instead of cotter pins on the rods. Obviously, those need to get replaced
I see the parts lists calling for plain steel cotter pins. I have quite a few aircraft grade parts, in stainless. Is it ok to use what I have, or is there a reason to prefer plain steel over stainless for this application?
TIA . . .
